I have a 75 gallon aquarium with 3 adult female guppies and roughly 35+ young guppies of all sizes. I have 3 amazon swords (1 large, 2 small), about 15 aponogetons, and a driftwood arrangement. The lighting is a Reptisun 5.0 that runs 12 hours a day, the filter is a Rena Filstar XP4, and substrate is sand. There is no lid on the aquarium. It's 70-75*F at all times, and the water is pretty calm. The filter outlet is below the waterline and I don't have any airstones.
I think that covers everything.
This is my guppy breeding tank. I'm looking for something -- anything -- to take care of the algae that grows on the glass, sand, and plants. I'm not too particular about WHAT it is, as long as it doesn't breed out of control, take over the tank, get too large, or eat my guppies/guppy fry or live plants. And because I don't have a lid, it also can NOT leave the water.
I don't care if it is a snail, shrimp, fish, etc. I'd like it to be as small
as possible, yet I'd prefer to not have snails. I'm open to all
I was looking at the pitbull plecos. Any other options or suggestions? I don't mind having several to get the job done, I just don't want it to turn into an algae-eater-breeding-tank, and I don't want to have to build a pond to contain it later in it's life.
(That is, NO large plecos! Yikes.)
